Jamaal Charles, Chiefs: The former UT back ended last season by rushing for more than 100 yards in four straight games, but the Chiefs added Thomas Jones over the offseason. Jones is proven and could take goal-line carries from Charles.

Knowshon Moreno, Broncos: He’s out with a hamstring injury, and while the second-year running back should be OK for Week 1, owners must hope the problem doesn’t linger.

Texas teams

Cowboys: While Marion Barber is the starter, Felix Jones is the more explosive back, and there’s reason to wonder if he’ll see more carries as the season progresses. Despite his impressive performances, Tashard Choice is the third back and merely late-round insurance.

Texans: After shining as a rookie, Steve Slaton struggled last season and Arian Foster impressed late in the season. Foster is the starter now and a good pick, even though the Texans drafted Ben Tate.
